I miss her

I just miss her so much. Its been 2 months since we’ve broken up, and I want her back so badly. I’ve contacted her 4 times and she’s rejected every attempt. I don’t know what to do…I feel so pathetic. I don’t even have an ounce of self-respect left. When will this feeling stop? I’ve tried everything…gym, journaling, meditation, talking to friends about it, and I’m still suffering. Even during the middle of work when I’m busy she’ll pop up in my mind. We were together for 2 1/2 years. Has anyone ever experienced this? Is it just over? Will she never come back? No one ever cheated or did something terrible. I just don’t get how she moved on so quickly. There is no other guy before someone says that.
